im in the process of removing some emissions stuff because none of it is hOoked up properly and I believe my fuel pressure regulator is suffering from little to no vacuum I have 2 questions.
1) is the vacuum line directly ported on the intake tube before the throttle body server as adequate vacuum?
2) would it be safe to run the vacuum line for the gas tank vapor line to the same vacuum line?

Thanks for looking and I hope I can get direct answers as the vacuum system is kinda new to me. I mean the tube sucks, it should work.

So for your FPR... you are running it of the the vacuum port on the throttle body?

Pretty sure you want it off the intake after the throttle body.

Eh I would vent gas tank as it should.

So it needs constant vacuum?

The emissions vacuum lines are coming out but I have plans to pass Cali smog this year and the tank evap line is something tested.

pretty sure if you had all emissions and brake booster removed the only vac line needed is the FPR and is like 2" long. and comes off the back of the intake. (this is for KAe not sure on KAde)

Yeah, on the KADE the FPR gets vacuum directly from the intake manifold.
I'd assume the KAE would need the same.

After the throttle body?
